The CorMax KBs are inflatable bags that can be filled with water to create a hand held weight. The KBs are light and compact and are similar to a smaller version of the CorMax Commander. Sold in pairs.
Exercising with the CorMax range, the sloshing of water pulls and pushes you in every direction igniting your stabilizing & core muscles instantly and working them to the max. The less water fill, the more CorMax products increase their instability.
Each KB holds up to 1.5 gallons of water, providing a unique weight for working out with.
Every CorMax order will include a Filling Attachment to be used in combination with the CorMax Foot Pump. It is highly recommended to purchase the CorMax Foot Pump for optimal assembly.
